Abstract
This structural diversity of insects, and the biological variety it reflects, did not develop all at once. Insects as we would recognise them from modern forms have been around for at least 300 million years, as amongst the first major diversifications of arthropods on land. Over this vast period, we can detect several changes and transitions in structure that appear now to have been ‘pivotal events’ in leading to their success and fostering their recent abundance. However, the fossil record from which we infer those changes remains cryptic in places: assembling unambiguous evidence from ancient insect fossils is not always easy, and it is not surprising that uncertainties persist – or that the opinions of various specialists may differ widely over how particular fossils may be interpreted! In this chapter, some background to the information on insect evolution derived from the fossil record is outlined, together with its relevance to study of the insects around us today.
